Finite Element Analysis And Study Of Friction Welding Machine Spindle

Friction welding is a kind of high speed machining, as a promising technology for attention, friction welding processing technology development along with the progress of processing and manufacturing, makes the product yield is higher and higher, loss is more and more low. The development of the high-speed spindle and maturity is the key to achieve high speed machining. How to make power transmission more efficient, more stable processing, and to realize high speed machining is very important.Structural design, static and dynamic characteristics of spindle to a large extent determines the high speed machine tool machining quality and working ability, also influences the machining accuracy. Optimization of the spindle structure and static and dynamic study, to further improve the working performance of high speed machine tool has a vital significance.By finite element method, based on software ABAQUS, butt welding machine spindle modeling simulation, considering factors under various working conditions, analysis of static and dynamic characteristics of spindle; and by using the LABVIEW software static and dynamic characteristics of spindle. Specific research contents are as follows:1. Analysis of the welding machine spindle structure characteristics, and its static anddynamic characteristics of the influence. Determine the main parameters of weldingmachine spindle.2. Welding machine spindle for more precise three dimensional finite element modeling,using ABAQUS calculation and analysis, get the spindle modal harmonious response;the spindle of the inherent frequency, vibration mode, analyze its influence on thespindle, extraction set point displacement offset.3. Dynamic analysis was carried out on the main shaft, set point displacement offset,and the modal displacement offset the same specified points during consolidation.4. Welding machine spindle dynamic testing system, using LABVIEW software and displacement sensor on the dynamic response of the main characteristics of experimental research.
